I was researching the idea of floor beds when I saw this awesome crib mattress topper. It looks cozy and is totally natural. I am in love and seriously considering getting this for DS. It might make him sleep in his cosleeper, since he only sleeps on our bed and I think it's because it's so much softer than his mattress. (I've already tried the smell thing, but it doesn't seem to work so that's why I think it may be his mattress)
